DEVICE FOR POINTING BRICK WALLS.

Specification of Letters Patent.

Patented June 8, 1915..

Application filed October 27, 1913. Serial N 0. 797,681.

To all whom it may concern.

Be it known that I, RICHARD H. CHAP- rnLL, a citizen of the United States, residing at Rolla, in the county of Phelps and State of Missouri, have invented certain new and useful Improvements in Devices for Pointing Brick lValls, of which the following is a specification.

My invention relates to bricklayers tools and appliances, and particularly means for pointing up brick walls.

The primary object of my invention is the provision of a very simple and readily manipulated device whereby the seams between the bricks of a wall may be pointed up and filled with mortar, cement or like semi-fluid material.

A further object is the provision of a device of the character described embodying a tuck trowel and a mortar holder, with means for forcing the mortar into a seam between the bricks of a wall.

A further object of the invention is to provide an improved form of piston for the mortar carrier, this piston being so constructcd that it will be properly guided in the mortar carrier and not be liable'to slide unequally.

A further object of the invention is to so construct the trowel that it will tuck, smooth,

and compact the mortar between the bricks.

A further object is to so form the piston that the packing around the periphery may be readily applied or removed, when desired. Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of my improved implement the scam between two courses of brick, the brick being broken away, to show the man nor in which the mortar is applied. Fig. 2 is a longitudinal sectional view through my device. Fig. a vertical section on the line 33 of Fig. 1. Fig. 4 is a like view to Fig. 3, but showing the manner in which the pointing device is used when the bricks of two courses are not flush with each other. Fig. 5 an under side view of one form of trowel. Fig. (l is a like view to Fig. 5 but slmiving another form of trowel. Fig. 7 is a front view of a trowel having a beading lug, or tuck upon its under face. Fig. 8 is a transverse sect on across the trowel-,pn the line S-8 of Fig. 5.

as applied to pointing up Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the 'samereference characters.

Referring tothese drawings it will be seen that my improved pointing device consists of a receptacle or mortar carrier designated 2, this receptacle in the embodiment of my invention illustrated being circular in cross section. The forward end of the receptacle isscrew-threaded or otherwise formed so as to engage with a cap 3. From this cap projects a discharge tube 4, which tube is illustrated asgradually contracted toward its outer end. The outer end of the tube is adapted for engagement with a trowel as will be later'described. The end of the receptacleQ opposite the cap 3 is open and disposed within the cylindrical receptacle 2 is a piston 5 ot-any suitable or ordinary form from which extends the piston rod 6. This piston rod projects beyond the open end of the receptacle 2 and is provided at its extremity with a. handle 7. As illustrated, the piston comprises the spaced disks 8, which preferably are made of sheet metal, and an intermediate wooden disk 9 having a central square or many sided opening 9 within which is disposed a. nut 10. The disk 9 is smaller in diameter than the disks 8 to provide for a packing 11 which may be wrapped around the peripheries of the disk 9. I find it convenient to form this packing of cloth or tape. It will be obvious that other packing may be used. This pa cking may be readily removed from the piston, if'it is necessary at any time, and as readily renewed. Leather disks used between the metallic disks 8 would soon become hard and burnt and would readily cut out. The cloth wrapping, however, remains soft and pliable, and if by chance a grain of sand were caught between the edge of the packing and the metal cylinder, the sand would be pressed into the cloth and thus would not scar the cylinder.

In order to provide a guide for he piston which will hold the piston in position at right angles to the axis of the receptacle 2, I mount'upon the rod 6 a spider 12 having a plurality of radially directed arms each at its outer end, being bent parallel to the wall of the receptacle 2. The extremity 13 of each of these parallel portions are bent at right angles so as to abut against the inner face of the piston. The screws 14. pass turned portions of the spider. The extremity of the rod 6 is screw threaded for enis slightly angular in cross section,

' the trowel plate transversely is of particular or tucks,

gagenient with the nut'10, while a' sleeve 15 spaces the center of the piston from the center of the spider. y

. Mounted on the end of the discharge tube 4 is a trowel plate 16. This consists of a plate of metal of any suitable shape, but preferably rectangular. The forward and rear extremities of the trowel plate are turned upward as at 17 and the trowel plate as illustrated in Fig. 8. This slight angularity of importance, as will presently appear.

The trowel plate is formed with an aperture 18 at its center from which extends an upwardly and rearwardly inclined socket 19. This socket engaged with the tube 4 by means of screw threads, or has a slip jointengagement with the tube 4.

The under. side of the trowel plate 16 is provided with one or more mortar pressers designated 20. In Fig. 5, two of these tucks 20 are shown, while in Fig. 6, only one is illustrated, this one being designated 20. Each preferably consists of a nearly semi-cir 'iilar lug or protuberance formed uponthe under'face of the trowel,

and where two tucks are used they are disposed one at each endfiof the elongated perforation 18. g presser istapered from the middle its opposite ends so that the tucksar what elliptical in form; The tucks, either have a uniformly roundedsurfaceo a faceted surface, as preferred.

Preferably :each

ers or tucks are of such d1 that they wiil readily courses of brick and will travel alonf'" seam. Preferably the width of eachjt smaller than the width of the seam-,lhr narily to be'found in brick work. The tucksact to press and smooth the mortar-once? ment' discharged into the seam through the aperture 18. It is of course obvious that the shape of suit the exigencies of any particular piece of brick work, and that a plurality of trowels might be used interchangeably upon the tube 4 so asto adapt the device to all forms of work. A thumb-piece 21 is dis from and the piston is the seam it will or v dz'and 4, and is see press'f fit in the seam between. two

the trowel16 and-of the press ing members20 may be changed inform to- "trowel; Where'the-courses are of my invention will be it is desired topoint up the seams between courses of brick, the receptacle 2 is filled with mortar by removing the piston therethenreplaced. The proper trowel, of course,'has been applied to the discharge tube 4. The pressing members or tucks 20 are inserted in the seam beween the bricks and as the piston is forced gradually inward, the device is reciprocated along the face of the brick, the trowel 16 forming a retainer bearing against the face of the brick and supporting the device in proper position relative to the brick while the members 20 guide the device along the seam, at the same time acting to press down and smooth the mortar or other semi-fluid material discharged from the receptacle 2.

' The members 20 act topress and compact the mortar discharged beneath the trowel and form a smooth pointing surface extending entirely along tar, of course, fills the spacebetween the inner ends of the pressing members 20, and when the trowelis pushed or pulled along leave a round or hollow seam without sharp corners regardless of the width of the seam.. If the edges of the brick are chipped, the mortar will flow or be forced into these chipped edges,=thus-jfilling up all-rough places.

As before stated, the trowel is slightly angular in cross section. this angularity is illustrated clearly'in Figs. to adapt the trowel to be sed for pointing up the seams between purses of brick which will not aline with ach other. j-In Fig. 4 is course A'is lower shown a case where the than the course B. If the trowel were flat. upon its under face the trowel would be inclined sothat only one ofthe trowel' would contact with the Asia-consequence the mortar would escape mto the space between the f trowel and the edgeof the brick, but by havthe under however,

The mor- The purpose oftheftrowel may betilted to the will contact withthefopposite face of'the 7 level, as in This allows the edges of the brick to press tightly against the under face of the trowel regardless'of the width'of the mortar between the brick, and this prevents the mortar from oozing-out onto the face of the brick. The construction of the trowel shown in Fig. 6 is for the purpose of leaving the mortar flush with the face of the brick. In this case the lug 20 is merely a guide lug. I

My invention is very simple and Fig. 3, the trowel is disposed on a level and I not. inclined.

pointing up old walls from which the mortar has fallen away from'the seams and will permit the work to be done very much more expeditiously than is possible by the hand pointing in use today. It is also to be noted that by providing tucking beads or lugs at each end ofthe trowel plate the trowel may be either reciprocated or pushed in either direction in order to point up the mortar. This construction therefore permits the operator to start in a corner to fill up the point between the courses of brick.

. While I have illustrated what I believe to be the best form of my invention, I do .not wish to be limited to this as it is obvious that many changes mightbe made therein without departing from the spirit thereof.

Having thus described the invention wha is claimed as new is p j 1. A pointing device of. the character described including a trowel plate having a discharge aperture, alining members disposed on the under side of the trowel plate forward and rearward of said aperture, said members being tapered towardthe adjacent ends of the trowelplate and adapted to en gage in the seam between two courses of brick, a mortar receptacle communicating with the aperture in the trowel plate, and means for discharging mortar from said receptacle.

2. A. pointing device of the character described including a trowel plate having a discharge aperture and less in widththan the trowel plate, alining members disposed on the under side of the trowel plate forward and rearward of said aperture, said members being rounded in cross section and tapered toward their opposite ends.
